The introduction of the new IR35 “off-payroll” working rules changed how contractors working in the public sector are taxed. These rules were introduced to ensure that individuals who work like employees pay broadly the same Income Tax and National Insurance contributions (NICs) as permanent employees.
The legislation mainly affects contractors who provide their services through a Personal Service Company (PSC) or another intermediary. When the rules were first introduced, they applied only to public sector engagements and did not affect contractors working solely in the private sector. Understanding these changes is important for both contractors and the organisations that hire them.
‘New’ IR35 rules
The new IR35 or “off-payroll” working rules apply to contractors who provide services to public sector organisations through an intermediary or Personal Service Company (PSC).
Under these rules:
- Contractors providing services through a PSC may be treated as employees for tax purposes.
- The public sector organisation hiring the contractor is responsible for deciding whether the engagement falls within the off-payroll rules.
- The contractor’s intermediary or PSC no longer decides the contractor’s employment status.
- The organisation or agency paying the contractor, known as the fee payer, must deduct PAYE and National Insurance contributions before making payment where the rules apply.
- For tax purposes, the fee payer is treated as the contractor’s employer and is responsible for meeting the relevant payroll obligations.
These changes were introduced to make tax treatment more consistent for contractors working in roles similar to employees.
Date the new rules will apply
The off-payroll working rules applied to payments made on or after 6 April 2017.
Any public sector contract that continued beyond this date became subject to the new legislation, even if the contract had originally been agreed before 6 April 2017. Contractors and public bodies therefore needed to review existing agreements to ensure they complied with the updated rules.
How contractors can protect themselves
Contractors working through Personal Service Companies or intermediaries should carefully review both existing and new contracts to understand how the off-payroll rules may affect them.
Before accepting new engagements, contractors should discuss their employment status with the hiring organisation, ensure contracts accurately reflect their working arrangements, and keep records of all agreements. Seeking professional advice from an accountant or tax specialist can also help contractors understand their obligations and reduce the risk of future disputes with HMRC.
Preparing in advance can make the transition to the new rules much smoother.

Reasons for ‘new’ IR35 rules
HMRC introduced the off-payroll working rules to reduce tax avoidance involving contractors who operated through Personal Service Companies.
Previously, some contractors working in roles similar to employees paid less Income Tax and National Insurance by providing their services through a PSC. The new rules were designed to ensure that contractors carrying out similar work to employees paid broadly comparable levels of tax.
As part of the changes, the previous 5% allowance available to PSCs for administering IR35 responsibilities was removed to simplify the process.
The rules affect certain contractors
The new IR35 off-payroll rules primarily affect contractors who work for public sector organisations through a Personal Service Company (PSC) or another intermediary.
They also impact:
- Public sector organisations engaging contractors.
- Recruitment agencies supplying contractors.
- Partnerships and intermediaries involved in contractor arrangements.
- Fee payers responsible for processing contractor payments and deducting employment taxes.
Each party has specific responsibilities under the legislation, making it important to understand how the rules apply in practice.
The rules that do not affect agencies
There are situations where the new off-payroll working rules do not apply.
For example, the rules generally do not apply when:
- An agency employs the contractor directly and operates PAYE and National Insurance through its payroll.
- A contractor is genuinely engaged as self-employed and the off-payroll rules are not triggered.
Each working arrangement should still be assessed individually, as employment status depends on the actual relationship rather than simply the wording of the contract.
The IR35 digital tool to determine a contractor’s employment status
To help organisations apply the legislation correctly, HMRC introduced an online employment status tool before the rules came into effect.
The digital tool helps the fee payer:
- Decide whether the off-payroll working rules apply.
- Determine whether the contractor would be regarded as an employee if no intermediary existed.
- Produce an employment status decision to support payroll and tax obligations.
Using accurate information when completing the assessment is essential, as incorrect details may lead to an inaccurate employment status decision.
Risk of HMRC IR35 investigation under new rules
Contractors working through a Personal Service Company whose contracts continued on or after 6 April 2017 could face an increased risk of an HMRC IR35 investigation.
Because public sector organisations are required to apply the off-payroll rules to relevant payments made after this date, HMRC may review contracts where there is uncertainty about a contractor’s employment status. Contractors should therefore keep copies of contracts, invoices, employment status decisions, and records of their working practices.
Maintaining clear documentation and seeking professional advice where necessary can help demonstrate compliance and reduce the likelihood of disputes if HMRC carries out an investigation.
